AIR Y OR. OTHER GASEOUS1-FLU-ID -HEATING' FURNACE.

Application filed March 19, 1923;

Gaseous-Fluid Heating Furnaces, of which.

the followingds a specification.

This; invention relates to the transmission ofheat to a moving fluidin apparatus'of'the type consuming acombustible gaseous mixtureof1two-constituents say, for example, gas and air correctlyproportioned at cons tantly related pressures abovethatof the,

atmosphere for" complete combustion in a chamber to whichonly. the controlled gaseous fluids are-admitted, andfrom which the products 'ofa combustion are expelled Withoutbeing drawn orsucked, by a reduced pressure such asresult's from a chimney orequiv alent device.

In apparatus :for transmitting heat from one: to another of two fluids-which are separated by a heat transmitting partition or wall, itis desirable that the counterflow system or movement of the two fluids'in oppo sitedirections-beadopted, and if the movement of the fluid whichis being heated can i be effected as the result-of the heat imparted thereto, the apparatus is correspondingly simplified. Such an arrangement calls for anupward movement ofthe -fluid which is being heated and consequent downward movement of'the heating medium, together with more or less upright partitions, but if considerable bodies of upwardly and clownwardly moving *fluids-are-to flowat a suitable speed over upright partitions, the height of the apparatus is liable to become obj e'ctionably extended.

The object of the present invention is to overcome such-diiliculties and provide compactapparatus for" satisfactorily heating considerable quanti-tiesof gaseous fluid.

The invention consists in the improved construction, arrangement and combination of parts hereinafter fully described and afterwardsspecifically pointed out in the ap pended claims.

Referring nowto the accompanyingdrawings':

Figure' l'is a-plan'vie-W partly in section of'apparatus in accordancewith the invention, and" Serial No: 626,190.

Figure 2 is a side view of the heating device, one half shown; in section and the other in elevation In :the arrangement shown by Way of 1 eX- ample in the drawings, a-combustion cham-- her a formed of metal shell a" lined With refractory material a is provided with a cover a and is carried upon a conduit structure or heat; transmittin appliance as here-- inafter described.

The combustion chamber at has suitable metal, sockets b connected-thereto, saidsock ets being adapted torreceive'burners 0, say of the'type describedin my United States Patent No. l,t19,054- of.June 6th, 1922;andcomprisingachamber c provided-ivith a longitudinally adjustable tubular member 0 wherein is a thirdadjustable member 0 the chamber 0 having an orificeo 'and tubular member 0 having an orifice 0 in=both diseshaped ends of said elements closely adja-- cent to the combustion chamber-so that the relative proportions of the two constituents of acombustible mixture may be adjusted close. to the combustion Zone. The mixture is admitted to the combustionchamber through a refractory channel or port a \vhichiis enlarged,-as shown at a prior to its entry into the combustion chamber.

The-burners-c at the end remote from-the combustion zone are each fitted with two boxes 0* and a, to which constituents ofa combustible mixture, for example gas and air, are supplied through pipes (L d from a pressure balancingidevic'e d say in the manner described in my United States Patent No. 1,347,955 of July 27th, 1920.

The conduit'structure or heattransmitting appliance e is formed of-a-series of superimposed hollow cylindrical or like elements, and consists in the embodiment illustrated of' three tubular elements 6 formed. of say 9-inch lengths of 4-inch gas tube threaded at each end and. screwed into flanges 6 e Theflange 0 may be of any ordinary type-adaptedto form a seating or base for the conduit structure, and the flanges e are, asshowninthe drawing, provided with recesses e for the reception of: disc elements 6 which are fastened together byflanges c and form'cylindrical-"or disclike elements of a diameter manytimes'exs ceedinjg" their length. and" alternating in the structure with thetubula-r elements 6'.

It-will be evident" that flanges such as 1 6 e can be cast in one with the disc parts 6' provided a pattern for the latter has movable pieces corresponding to 6 6 Within the large diameter disc-like elements are central deflecting plates f which extend to within a short distance of the inner circumference or the disc-like elements and thus divide the interior of the disc-like elements into two circular flat conduit chambers g communicating with one another only round their outer edges at g. The plates f are held in position by distance pieces h consisting of columns or struts with abutments attached by screw threads to the ends thereof so as to render the length readily adjustable.

For supporting the combustion chamber a upon the top of the conduit structure 6, a flange c is provided having a cylindrical extension 6 which fits within the shell (4 of the combustion chamber.

The combustion chamber and conduit structure are enclosed within a housing j which is supported upon a metal base ring or stand of channel or trough-like crosssection and provided with four or any other convenient number of legs in by which it is held above the ground level at a suitable distance for permitting the entry of the air which is to be heated.

The housing j consists ot'three rings or belts j of plate material and two annular 'baifle plates j extending inward from the housing to within a convenient distance of the tubular members 6. A supporting cover 7' is also provided at the top of the housing and the whole is covered with a lagging i of suitable non-conducting material to prevent radiation of heat from the apparatus.

The annular battles 7' are conveniently provided with registering bands 3' around their perimeters for registering with the shell members j, and distance pieces h of a construction similar to the distance pieces h, but considerably longer as may be necessary, are conveniently employed for positioning the baflles and disc-like members in relation to one another.

lVhen operating in accordance with this invention, a combustible gaseous mixture correctly proportioned for complete combustion in the burners 0 is consumed in the com bustion chamber a, and in view of the pressure being in excess of the pressure of the atmosphere, the products of combustion are expelled downwards through the flat conduit passages of the disc-like members and through the tubular elements 6 until they finally escape along a flue or the like m from which they are, in a cooled condition, discharged to the atmosphere at a point prei erably below the level of the combustion chamber.

The air in the housing j is heated by contact with the disc-like members and combustion chamber and rising draws in a fresh in counter-flow to the products of combustion until it finally reaches the top of the apparatus where it passes into a distributing head of any known type and thence into suitable ductscommunicating, say, with the various rooms of a dwelling or the like which is to be heated, or the appliance may be used for supplying heated air for any other purpose or for heating any other gaseous medium, the temperature of which is to be raised.
